In AustralianAntarcticDataCentre/availability: Estimating Geographic Space Available to Animals Based on Telemetry Data

Randomized track

Description

Compute surrogate track by randomizing the steps of an observed track

Usage

randomize_track(lonlat, rotate = c(-pi, pi), reorder = FALSE)

Arguments

lonlat	a 2-column matrix or dataframe with longitude and latitude of each point
rotate	a 2-element numeric vector giving the lower and upper limits of the random rotation to apply to the randomized track
reorder	should the track steps be randomly reordered.

Details

Converts a track to a distance/bearing representation, and then reconstructs a new track by randomly perturbing the bearings of each increment, and otpionally, randomly reordering the increments.

Value

A dataframe with columns

lon	the longitude of the randomized track
lat	the latitude of the randomized track
